matlab激活出错 License checkout failed. License Manager Error -9

Matlab激活成功后，在启动的时候出现如下的错误窗口

很显然是在注册的时候，Windows用户名填写的不正确导致的

查看windows用户名的方法是在命令行中输入net user

需要重新进行激活，方法如下，需要在安装目录中找到激活matlab的可执行程序，如下

If MATLAB will not launch

If you have an expired or otherwise unusable license, MATLAB may not be able to launch. In this case, you will need to launch the MATLAB activation client directly. To find the MATLAB activation client on each OS:

Windows

The activation client is located here:

C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe

Mac

• Open Finder.
• Go to "Applications".
• Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2015b.app)
• Click on "Show Package Contents".
• Open "Activate.app".

Linux

The activation client is located here:

/usr/local/MATLAB/R20XXx/bin/activate_matlab.sh
